Abstract: An encryption method implemented by a terminal having an operating system that can be accessed by several users and an encryption module for encrypting data intended for another terminal. The method includes a detection step for detecting when a session for accessing the operating system is opened by a user. In response to the detection of such a session being opened, the method continues with a step of setting the parameters of the encryption module with an encryption key unique to the user for encrypting data intended for another terminal, in which the encryption key is generated by the terminal, or is stored in a memory of the terminal before the detection of a session accessing the operating system being opened.

Abstract: The invention relates to a method for establishing a virtual private network between local area networks, each local area network comprising at least one access gateway to a public network and a unit comprising a VPN client, the method comprising the following steps carried out each time a unit is powered on: sending, by the unit, of at least one connection message to an infrastructure connected to the public network and comprising at least one intermediate server, each connection message passing through a respective gateway of the local area network; reception, by the infrastructure, of each connection message; and determination of topology data identifying each bridge of the local area network in which the unit is placed, the method further comprising the following steps carried out for a plurality of units: instancing, by a predetermined intermediate server of the infrastructure, of a VPN server associated with the plurality of units; establishing an encryption tunnel between the VPN server and the VPN cli

Abstract: The invention proposes an encryption method implemented by a terminal comprising an operating system that can be accessed by several users and an encryption module for encrypting data intended for another terminal, the method comprising a detection step (100) for detecting when a session for accessing the operating system is opened by a user, and, in response to the detection of such a session being opened, a step (104) of setting the parameters of the encryption module with an encryption key unique to the user for encrypting data intended for another terminal, in which the encryption key is generated (101) by the terminal, or is stored in a memory (16, 22) of the terminal before the detection (100) of a session accessing die operating system being opened.
